  • Les statuts des instances de mutualisation

    13 mars 2010, par

    Pour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
    Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...)

  • Transcoding hevc to h264 using GPU and scale_npp

    19 mai 2022, par JanZg

    I am trying to transcode hevc to h264 using GPU. Default input is 10 bit hevc but I also try it on 8 bit hevc. I use hevc_cuvid decoder and h264_nvenc encoder. While scaling using CPU its correct. I was also using scale_npp=w=1280:h=720:format=yuv420p and scale_cuda - > no result.

    


    Working command without using GPU to scale :

    


    /usr/local/bin/ffmpeg -y -v warning -c:v hevc_cuvid -an -sn -dn -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_on_network_error 1 -i http://1.2.3.4:8794 -c:v h264_nvenc -pix_fmt yuv420p -vf scale=1280:720 test_hevc.mp4


    


    But when I try to scale using GPU for example scale_cuda or scale_npp I get this error :

    


    Command :

    


    /usr/local/bin/ffmpeg -y -v warning -c:v hevc_cuvid -an -sn -dn -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_on_network_error 1 -i http://1.2.3.4:8794 -c:v h264_nvenc -pix_fmt yuv420p -vf scale_npp=1280:720 test_hevc.mp4


    


    Outputs :

[NULL @ 0xb7520490] Requested output format 'mpeg' is not a suitable output format
    
VID_20150514_184208.mp4.0.mpg: Invalid argument

    But I keep getting an error saying "Requested output format ’mpeg’ is not a suitable output format". The same command seems to work on my Ubuntu machine with a full build of FFmpeg. What am I missing ? I thought I had all the mpeg encoders/decoders enabled ... mpeg, mpegvideo, mpeg1video, mpeg2video.
